Abstract

The invention discloses a dual-quantization injector special for insulin, which relates to an injector and is used for solving the problem that the conventional insulin injector has high manufacturing cost and cannot ensure sterile injection. The head end of a tubular bottle filled with insulin is detachably connected with a needle head cap; a needle head hole in the needle head cap is communicated with the tubular bottle filled with the insulin; one end of a piston propelling screw rod is in threaded connection with a piston, and the other end of the piston propelling screw rod is detachably connected with a cap type thrusting head; one end of the piston and one end of the piston propelling screw rod are arranged in the tubular bottle filled with the insulin; the piston is slidably connected with the tubular bottle filled with the insulin; an adjusting quantitative ring is arranged outside the tubular bottle filled with the insulin and is in threaded connection with the piston propelling screw rod; the outer wall of the piston propelling screw rod is provided with a plurality of measuring lines along the axial direction; the plurality of measuring lines are uniformly distributed along the circumferential direction of the piston propelling screw rod; and the thread pitch P of the piston propelling screw rod is equal to 2mL / n. The injector can be applied to injection of insulin.

Description

technical field [0001] The present invention relates to a syringe. Background technique [0002] There are two types of insulin syringes currently on the market: syringe indwelling needles and pen-type syringes. The traditional way of indwelling needles in syringes is to inhale and pressurize drugs under negative pressure. Patients need to inject at least once a day, so it is impossible to guarantee drug inhalation and injection under sterile conditions; while the current pen-type syringes are expensive and increase financial burden on patients. Contents of the invention [0003] The object of the present invention is to provide a special injector for dual-quantitative insulin, so as to solve the problems of high cost and inability to guarantee aseptic injection of current insulin injectors. [0004] The technical scheme adopted by the present invention to solve the above-mentioned technical problems is: the syringe includes a tube bottle containing insulin, a piston, a ...
